#include <itkLaplacianOperator.h>
A NeighborhoodOperator for use in calculating the Laplacian at a pixel.
A NeighborhoodOperator for use in calculating the Laplacian at a pixel. The LaplacianOperator's coefficients are a tightest-fitting convolution kernel.
For example, the simplest Laplacian Operator for 2D has the form:
